3,045,417 'SPlNNING RING WITH WICK IN HOLDER Andrew J. Wayson, Needham, and Angelo G. Bucchianeri, Millis, Mass., assignors to Merriman Bros, Inc., Boston, Mass., a corporation of Massachusetts Filed Oct. 19, 1960, Ser. No. 63,590 2 Claims. (Cl. 57-120) This invention relates to the textile industry and is particularly concerned with an improvement in spinning rings and holders therefor. The invention more specifical- 1y relates to the manner in which a lubricant carrying wick is associated and maintained in engagement with a spinning ring of porous material, such as powdered metal, whereby the lubricant, usually oil, may be absorbed by the ring and transmitted to its surface to lubricate the traveler.

In the practice of our invention, in a preferred embodiment thereof, we employ a spinning ring holder in which is mounted an oil absorbent powdered metal ring. We use a wick to carry oil to the ring from an oil reservoir adjacent the holder. As distinguished from the prior art, the Wick isinitially mounted in the holder rather than in the ring prior to the positioning of the ring in the holder. Thus, before inserting the ring in the holder, the wick, running from the oil source, is passed laterally through the holder wall and positioned in a circumferential channel formed in the interior face thereof. The ring, grooved exteriorly to cooperate with the holder but with no wick in the grooves, is then placed within the split-type holder which is spread to receive it.

A further feature of our invention is that the wick, while positioned in the holder, extends substantially all the way around. the ring. The gap in the wick at the split in the holder is so short that the lubrication of the traveler is unaffected.

These and other objects and features of our invention will appear as the description proceeds with the aid of the accompanying drawings, in which:

FIG. 1 is a plan view of the spinning ring assembly with the ring cut away at the split portion of the holder;

FIG. 2 is a fragmentary sectional view in side elevation taken on the line 22 of FIG. 1;

FIG. 3 is a sectional view showing in greater detail the interlocking arrangement of the ring and holder disclosed in FIG. 2;

FIGS. 4, 5 and 6 are sectional views of alternative constructions.

Referring first to FIG. 1, we employ a holder 10 of metal or other suitable material which is formed with slotted cars 12 and 14 for securing the holder to a spinning frame (not shown). The ring is split at 16 so that the holder 10 may be spread to receive a spinning ring 28. A bolt 18 extending through extension 20 and threaded into extension 22 provides means for clamping the holder about the mug.

The ring 28 is formed of oil absorbent material, preferably the conventional sintered powdered metal, and is dimensioned to fit inside the holder 10, leaving annular rounded top and bottom faces 30 and 32 extending above and below the holder 10. A conventional traveler 33 is shown mounted in operative position on the ring in FIG. 1.

The interior face 34 of the holder 10 is substantially cylindrical, being broken at the previously-mentioned split 16. In the preferred embodiment, the interior face 34 of the holder 10 is grooved circumferentially to provide upper and lower parallel circumferential flanges 36 and 38. The flanges 36 and 38 thereby define a channel 40 in the interior face 34 of the holder 10. This preferred embodiment is illustrated in section in FIGS, 2 and 3.

The channel 40 extends circumferentially around the interior face 34 of the holder 10, terminating, however, as

nited States Patent shown in FIGS. 1 and 2, at 42 and 44 just short of the end radial Walls 43 and 45 at the split 16.

A wick 46 comprising a strand of suitable material, shown in elevation at the central part of FIG. 2 and in section in FIG. 3, is placed in the channel 40. This is accomplished by first passing the wick 46 through a passage 48 (see FIG. 1) leading from anoil reservoir, hereinafter to be described, to the channel 40. The wick 46 is then laid in the channel 40 in any convenient manner. For purposes of example, the wick 46 may first be laid in a clockwise direction in channel 40, in which case it runs up to the end face 42, as shown in FIG. 2, then doubles back on itself in counterclockwise direction for almost a full circle until it reaches the end face 44. It is then again doubled back to run clockwise to and through passage 48 into the oil reservoir. In this way, a continuous wick member is inserted in the channel 40, presenting two wick surfaces, vertically disposed, which, when the ring has been inserted in the holder, will rest snugly against the ring Wall.

An oil reservoir indicated generally at 50 of standard design is provided asan integral part of the holder 10 and, as heretofore explained, communicates with the channel 40 by the passage 48. The reservoir 50, in a preferred -53 to felt 55 by a short wick 59 passing over a dividing wall 61. y

In the preferred embodiment herein described, the powdered metal ring 28 is made with an exterior circumferential channel or groove 52, shown in FIGS. 2 and 3. The channel 52 is dimensioned so that the holder 10 will fit snugly therein and hold the ring 28 securely.

Variations of the preferred construction are shown in FIGS. 4, 5 and 6. In FIG. 4, the holder 10 is constructed with three circumferential flanges S4, 56 and 58 forming two circumferential channels 60 and 62. A wick similar to the wick 46 is placed in each channel, whereby oil may be supplied to the ring 28 more rapidly. The ring 28, in this case, is constructed with an exterior circumferential channel 64 dimensioned to receive the vertically widened holder 10.

In FIG. 5 is shown another variation in which the circumferential flanges 54, 56 and 58 of FIG. 4 are slightly extended and are received into narrow circumferential channels 66, 68 and 70' in the exterior face 72 of the ring 28. In this embodiment, the wicks abut exterior face 72 thereof.

Another embodiment, shown in FIG. 6, is characterized by a relatively wide shallow channel 74 in the face 34 of the holder 10. The holder 10, as in the previous examples, fits into a cooperating channel 76 in the exterior face 72 of the ring 28. The doubled wick 80- is positioned in the channel 74 so that the surface of only one strand abuts the ring 28, whereas in all prior described embodiments the wick has presented two surfaces to the ring 28.

The assembly of the spinning ring is accomplished as follows:

The bolt 18 is unscrewed, permitting spreading of the holder 10. The wick, with its ends in compartment 51 and extending through passage 48, is located in channel 40, as above described. The ring 28 is then positioned over the holder 10 and, upon sufficient spreading of the holder at split 16, may be inserted in the holder in engaging position. The bolt 18 is then tightened, closing the holder 10 and firmly locking the ring 28 therein.

The operation of the assembly is as follows:

Oil is supplied to the reservoir 53, passes by wick 59 to the metering felt 55 and thence to wick 46. The wick the uncut-away 46 carries the oil through the length of the channel in the holder. The ring in engagement with the Wick absorbs the oil and in due course the oil moves through the ring to the surfaces thereof, creating thereon an oil film sufficient to lubricate the traveler as it moves around the ring. The distance between the end Walls 42 and 44 of the Wick groove in the holder is so short that lubrication of the ring surface in this vicinity is unaffected, the oil moving readily to the surface area of the ring, spanning the split 16.

It is our intention to cover all modifications and changes of the examples of the invention herein chosen for purposes of disclosure which do not constitute departures from the spirit and scope of the invention.
